I am getting around to setting up shipping and payment on my ZenCart. UPS is the shipping method we'll use. Is there a good updated module I could use? I saw some threads and older mods but would like to find out what is the best way to deal with UPS. This is my first time with Zen Cart so please excuse the ignorance on this issue.
Zencart 1.3.8

Many Thanks,
Yolanda
